The design and color of the purifier are perfect to fit in with a lot of different decor without looking like an eyesore. It's very quiet and works fast to clean out a room. The sensor light comes on so it can turn on by itself when needed and the sleep mode has a very dim light so it doesn't light up your whole bedroom. I will be purchasing another so I don't have to move this one around. It has a nice carry handle and is lightweight.
